VENTILATING DEVICE FOR CARS.

SPECIFICATION forming part of Letters Fatent No. 521,617, dated June 19,1894. Application filed February 10, 1894:. erial No. 499,742- (No model.)

to heat a portion thereof so as to cause a positive circulation of air therethrough, these pipes extending from near the bottom of the car upwardly and discharging out doors, so as to take the foul air from the lower part of the car and carry it out.

The invention particularly further consists of the peculiar construction of air supply pipes and their valves and further in the peculiar construction, arrangement and combination of the various parts.

In the drawings, Figure l is a sectional elevation of a railway car embodying my invention. Fig. 2 is an enlarged, vertical section through one side of the car, showing the arrangement of the air escape pipes. Fig. 3 is an enlarged elevation of the inside of the car showing one of the air escape pipes and the air supply pipes. Fig. 4 is a section on line w as Fig. 3, and Fig. 5. is a diagram section similar to Fig. 2. showing a modification.

It is well known and generally admitted by all railroad men that the present construction of the ventilating devices for railway cars are entirely inadequate, usually consisting of the windows in the sides of the car and the ventilating windows in the roof.

My invention is intended to obviate these difficulties and yet so constructed that it may be applied to the ordinary type of railwa cars.

A represents the car platform, Bthe superstructure, 0 the windows of a car of ordinary construction. Between the windows or at any other suitable point in the car I arrange the vertical air discharge pipes D preferably between the inner and outer casing of the car sides, so as to be hidden from view, and having the offset E at the lower end terminating in a heating apparatus I preferably arrange the I hood F directly over the radiator and prefer to provide the radiator with a spur G entering the lower end of the pipe or hood, so as to create a positive circulation therein. In case gas is used in lighting the car if desired a jet of gas may be employed to create the necessary circulation in the pipe or any other heating means. able damper H, by means of which the amount of air circulated therethrough may be controlled. At the top, the pipe is provided with a lateral discharge I having its outer end preferably flush with the side of the car and covered with a screen or cloth J to prevent the possibility of ingress of dust or cinders. To further prevent the possibility of ingress of dust or cinders into the car, I preferably provide a dust trap K at the bottom of the pipe D and make the lower section or hood F with a dust trap detachable, so that it may be removed for cleaning purposes.

Beside the pipes D extending through the sides of the car I arrange the inlet pipes *L, provided at their outer end with a suitable screen orcloth 0, and at their inner end with a damper or valve P. This I preferably arrange in sleeping cars, as shown in Fig. 3, one for the top berth and one for the lower berth, so that without opening a window the occupant of either berth may be supplied with fresh air in any desired quantity and without danger of creating a draft. Thus it will be seen that every seat in the car will be provided, not only with the exit pipe through which there is a positive draft, taking the cold air and foul air from the bottom of the floor carrying it out of the car, but also induct pipes always under. the control of the occupant of the seat, by means of which he can regulate to a nicety the amount of fresh air desired.

This device is not only a desirable one because of its advantages in giving pure air and removing the foul air but also from the fact that it lessens the danger of taking cold which is 'a constant menace in the use of the win This pipe is provided with a suitdows of cars as now constructed when traveling in cold weather.

In Fig. 5 I show a construction especially designed for a smoking car, in which the pipe D is provided near its upper end with an aperture K controlled bya damper or valve K. This will be of use in clearing the car from smoke which when the damper K is opened will draw out through the aperture K What I claim as my invention is- 1. In a railway car, the combination with a series of air ed uct pipes extending from near the fioor of the car between the windows thereof and terminating at a point adjacent to the top of the car, of a removable section for the pipe formed with lateral hollow offsets, and a dust collecting pocket in line with the pipe and below the lateral passage in the offset, substantially as described.

2. In a railway car, an air educt pipe extending through the casing between the windows, a lateral olfset at the bottom, the head F extending downward inside the car, the radiator located directly below the head and having the spur G entering said hood, the lateral external discharge at the top of the pipe, and a valve H in said offset, substantially as described.

In testimony whereof I aftix my signature in presence of two witnesses.
